A method of generating a visual program summary is disclosed for a multiple source video feed. In the disclosed method, a computing device continuously captures frames from a set of available video feeds such as television channels. The computing device analyzes the captured video frames to remove redundant frames. The computing device then selects a set of frames to generate a visual program summary. The selected frames are composited together to generate a visual program summary.

6. The method of claim 1 , further comprising deleting a first video frame from at least one set of video frames of the plurality of sets of video frames prior to displaying the at least one set of video frames if the first video frame is redundant to a second video frame also from the same at least one set of video frames.
7. The method of claim 6 , wherein the color histograms of the first and second video frames are used to determine if the first video frame is redundant to the second video frame.
8. The method of claim 6 , wherein motion vector correlation is used to determine if the first video frame is redundant to the second video frame.
9. The method of claim 1 , further comprising deleting a video frame from at least one set of the plurality of sets of video frames if the at least one set of video frames spans a boundary such that the video frames of the at least one set of video frames span a plurality of video programs.
10. The method of claim 1 , wherein the regular interval of time is adjustable.
11. The method of claim 1 . wherein the set of channels excludes at least one channel that a viewer of the visual program summary has chosen to eliminate.
12. An apparatus comprising: at least one tuner to repeatedly tune at regular intervals to differing channels of a set of channels to receive video frames from each channel of the set of channels; a capture device coupled to the tuner to capture a plurality of sets of video frames, each set of video frames being comprised of a plurality of video frames received and captured each channel of the set of channels as each channel is repeatedly tuned to by the at least one tuner; a processing device coupled to the capture device generating a visual program summary comprised of at least two of the sets of video frames wherein the at least two of the sets of video frames are repeatedly updated by replacing those at least two sets of video frames with at least two more recent sets of video frames received and captured from the same channels of the set of channels from which the at least two sets of video frames were earlier received and captured as the same channels are repeatedly tuned by the at least one tuner.
13. The apparatus of claim 12 , wherein the capture device captures each frame that comprises at least one set of the plurality of sets of video frames at an adjustable interval.
14. The apparatus of claim 12 , wherein the capture device stores at least one video frame of at least one set of the plurality of sets of video frames as a digital video frame.
15. The apparatus of claim 12 , wherein the capture device comprises a television tuner and a video frame digitizer.
16. The apparatus of claim 12 , wherein the processing device adds at least a portion of textual information received with at least one video program depicted within a set of video frames to the visual program summary.
17. The apparatus of claim 12 , wherein the processing device accesses a program schedule and adds at least a portion of the information from that program schedule to the visual program summary.
18. The apparatus of claim 12 , wherein the processing device deletes a first video frame from at least one set of the plurality of sets of video frames captured by the capturing device if the first video frame is redundant to a second video frame also from the same at least one set of video frames.
19. The apparatus of claim 17 , wherein the color histograms of the first and second video frames are used to determine if the first video frame is redundant to the second video frame.
20. The apparatus of claim 17 , wherein motion vector correlation is used to determine if the first video frame is redundant to the second video frame.
21. The apparatus of claim 12 , wherein the processing device deletes a video frame from at least one set of the plurality of sets of video frames captured by the capture device if the at least one set of video frames spans a boundary such that the video frames of the at least one set of video frames span a plurality of programs.
22. The apparatus of claim 12 , wherein the set of channels tuned at regular intervals by the at least one tuner excludes at least one channel that a viewer of the visual program summary has chosen to eliminate.
